Lutetiumchinhu chisingawanike chepasi chine mitengo yakakwira, matura mashoma, uye mashoma ekushandisa. Iyo yakapfava uye inonyungudika mu dilute acids, uye inogona kuita zvishoma nezvishoma nemvura.
Isotopi dzinongoitika dzega dzinosanganisira 175Lu uye hafu yeupenyu hwe2.1 × 10 ^ 10 yemakore β Emitter 176Lu. Inogadzirwa nekudzikisa Lutetium(III) fluoride LuF ∨ · 2H ₂ O ine calcium.
Iko kushandiswa kukuru ndeyekukonzeresa petroleum kuputika, alkylation, hydrogenation, uye polymerization reactions; Mukuwedzera, Lutetium tantalate inogonawo kushandiswa sechinhu che X-ray fluorescent powder; 177Lu, radionuclide, inogona kushandiswa paradiotherapy yemamota.
Discovering History
Yakawanikwa na: G. Urban
Yakawanikwa muna 1907
Lutetium yakapatsanurwa kubva kuytterbium neFrench chemist Ulban muna 1907 uye yaivewo chinhu chisingawanikwe pasi pano chakawanikwa nekusimbiswa mukutanga kwezana ramakore rechi20. Zita rechiLatin reLutetium rinobva pazita rekare reParis, France, inova nzvimbo yekuzvarwa yeUrban. Kuwanikwa kwe lutetium uye imwe isingawanzo pasi element europium yakapedzisa kuwanikwa kwezvinhu zvese zvisingawanzo zvepasi zviripo mune zvakasikwa. Kuwanikwa kwavo kunogona kutorwa sekuvhura gedhi rechina rekuwanikwa kwezvinhu zvisingawanzo pasi uye kupedzisa nhanho yechina yezvisingawanzo kuwanikwa zvinhu zvepasi.

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d1
Lutetium isimbi chena yesirivha, inova simbi yakaoma uye yakaomesesa pakati pezvinhu zvisingawanzoitiki zvepasi; Kunyungudika 1663 ℃, kuvira poindi 3395 ℃, density 9.8404. Lutetium inenge yakagadzikana mumhepo; Lutetium oxide ikristaro isina ruvara inonyungudika mumaasidhi kuita munyu unoenderana usina ruvara.
Rare Earth metallic luster of lutetium iri pakati pesirivha nesimbi. Izvo zvisina kuchena zvemukati zvine chekuita kwakakura pazvivakwa zvavo, saka kazhinji pane misiyano yakakura muhunhu hwavo hwemuviri mumabhuku.
Metal yttrium, gadolinium, uye lutetium zvine corrosion resistance uye inogona kuchengetedza simbi inopenya kwenguva yakareba.
Application
Nekuda kwekunetsa kwekugadzira uye mitengo yakakwira, lutetium ine mashoma ekushandisa ekutengesa. Zvinhu zve lutetium hazvina kunyanya kusiyana nedzimwe simbi dze lanthanide, asi matura ayo ari maduku, saka munzvimbo dzakawanda, dzimwe simbi dze lanthanide dzinowanzo shandiswa kutsiva lutetium.
Lutetium inogona kushandiswa kugadzira mamwe alloys akakosha, akadai seLutetium aluminium alloy inogona kushandiswa Neutron activation ongororo. Lutetium inogona zvakare kushandiswa sechinhu chinokonzera petroleum kupaza, alkylation, hydrogenation, uye polymerization reactions. Uye zvakare, doping lutetium mune mamwe laser makristasi akadai seYttrium aluminium garnet inogona kuvandudza kushanda kwayo kwelaser uye kufanana kwemaziso. Uye zvakare, lutetium inogona zvakare kushandiswa kune phosphors: Lutetium tantalate ndiyo yakanyanya compact chena zvinhu inozivikanwa parizvino, uye chinhu chakanakira X-ray phosphors.
177Lu ndeye synthetic radionuclide, inogona kushandiswa kurapa radiotherapy yemamota.
